His father Placido Lopez, is a general repairman while his mother, Maria Jacoba Jaena is a seamstress. He studied at the Seminario Tejaro and at an early age: he was placed under the care of Reverend Francisco Jayme who enhanced and developed his skills in speech. Since his ambition was to become a doctor, he tried to enroll at the University of Santo Tomas but was deprived of access due to lack of requirements. While in the city, he worked as a trainee at San Juan de Dios Hospital but due to poverty he was forced to return home to Iloilo and continued his practice there. His encounter with other less fortunate Filipinos opened his eyes to the maltreatment and abuses of the Spaniards. He campaigned to voice out the injustices and wrongdoings of the Spanish colonizers. "Fray Botod", the story' of a fat and corrupt priest angered the friars more, thus his life was put in danger. He flew to Spain to avoid conflict but continued his battle. He was the leader in the literary faction and became its speaker, He pursued his study of medicine at the University of Valencia but did not complete the course and instead shifted to journalism.
